Abstract: Methods and devices for tissue fixation. A cortical button with a rib between two slotted openings. The rib increases the cortical button structural rigidity without increasing palpability. An adjustable loop construct with two discrete locking passages that provides manageable loop reduction and improved tissue coupling. The adjustable loop construct may be coupled to tissue via a passing construct. An assembly with a reduction bar, a button and an adjustable loop construct, the assembly provided assembled in a first configuration that disassembles to guide steps of tissue fixation. The reduction bar may be assembled to the reduction bar for reducing the adjustable loop construct.

Abstract: For a group of nickel-based superalloys, improved properties have been obtained by stabilizing at increased temperature for a reduced time relative to prior art specifications. In particular, improved creep properties have been obtained with a one-hour 1800° F. stabilization relative to a prior art four-hour 1500° F. stabilization.

Abstract: A method of repairing a braze joint and the resulting joint includes removing an unsuitable portion of a first joining material in a joint between a first member and a second member of an aerospace assembly and cleaning the joint. A stripping solution is used to remove the unsuitable portion of the first joining material. A first cleaning solution is used to clean the joint, and the joint is further cleaned using a second cleaning solution. During a rebrazing step, a second joining material moves into a void left by the removed unsuitable portion from the removal step to form a new joint between the first member and the second member that includes the remaining first joining material and the second joining material.

Abstract: Systems and methods for repairing Thermo-Span® gas turbine engine components are described herein. Embodiments of these methods minimize post-weld residual stresses in a weld repaired Thermo-Span® component by solution heat treating the component by heating the component to about 2000° F.±25° F., holding the component at about 2000° F.±25° F. for about one hour; and cooling the component to below about 700° F. at a rate equivalent to cooling in air; and precipitation heat treating the component by heating the component to about 1325° F.±25° F., holding the component at about 1325° F.±25° F. for about 8 hours, cooling the component to about 1150° F.±25° F. at a maximum rate of about 100° F./hour, holding the component at about 1150° F.±25° F. for about 8 hours, and cooling the component at a predetermined cooling rate. Dimensions of the fully-machined and weld repaired component are maintained during solution heat treating and precipitation heat treating via custom designed furnace tools.
